Specification of Letters Patent.

To all whom it may concern: 1

Be it known that I, JOHN P. GARDNER, a citizen of the United States,residing at Cairo, in the county of Alexander and State of Illinois,have invented new and useful Improvements in Weather-Strips, of whichthe following is a specification.

This invention relates to improvements in Weather strips and moreparticularly to a. construction of that type wherein the weather stripproper is fitted in a casing, set nto the bottom of the door and iscombined with certain elements whereby it may be projected to engage'thefloor or sill or retracted to disengage the floor or sill.

The present invention proposes certain novel features of constructioninvolving the projecting and retracting operations of the weather stripand whereby the latter functions as a weather strip when the door isclosed, and as a door holder when the door is fully opened, and alsowhereby a cushion-' ing action is secured as the door comes into eitherits full open or closed position, and

just prior to the engagement of the weather strip with the floor orsill. V

An embodiment of the invention is illustrated wherein Figures 1 and 2are views in plan and elevation of a door to which the improvement isapplied; Fig. 3 is a vertical longitudinal sectional view of theimproved weather strip organization; Fig. 4 is a sectional view on theline 4l4 of Fig. 3; Fig. 5 is a hori Zontal sectional view showing therelation of the parts of the weather strip organization when the doorreaches its open position; Fig. 6 is a detail perspective viewillustrating certain features of aconstruction of the slidable operatingrod; Fig. 7 is a similar view showing a projecting arm by which theaction of the rod shown in Fig. 6

is initiated when the door comes in open' osition; Fig. 8 is a similarview of a sleeve y which the parts shown in Figs. 6 and 7 are held inproper relation to one another; and Fig. 9 1s a similar view of agrooved plate which is fitted on a door jamb and cooperates with the armshown in Fig. 7

Similar characters of reference designate corresponding parts throughoutthe several views. j

The door has a bottom recess which ex tends approximately the full widththereof, as shown in Figs. 4 and 5, and in said reerably comprise aagainst a lug 9 in the accompanying drawings,

ccss there is fitted a casing l which has an approximately invertedU-shape in cross section, and which serves to confine and protect theweather strip proper, comprismg a body 2 of rubberor other suitableweather proofing material and a channel 3 in which said body is fittedand which, together with the body 2, is movable vertically of thecasing 1. r

The weather strip is to be projected from or retracted into the casing 1and the connections for achieving these operations prefrod 5 which isslidable longitudinally ofsaid casing and is supported in lugs 6depending from the upper wall of said casing, and levers 7 which arepivoted between their ends to a side wall of the casing 1 and at theirends are pivoted to the rod 5 and. to the channel 3 respectively, thepivotal connections of the levers 7 and the rod 5 consisting ofv thewell known slot and pin joint. The retraction of the weather strip intothe casing 1 is effected, preferably, by an expansive coil spring 8, theends of which bear against one of the lugs 6 and on the rod 5.

The ends of the recesses in which the casing 1 is fitted are closed byplates 10 and 11, and the plate 11 is provided with an opening 12through which works a rod mental to'the rod 5 and, in efl ect, formingan axial extension or continuation of the latter. When the weather stripis in retracted relation, the rod 13 is projected through the opening 12and as the door comes into closed position, the end of said rod engagesthe adjacent door jamb, such engagement manifestly being effective tomove the rod 5 against the tension of the spring 8 and to therebyproject the weather strip from the casing 1, as shown in Figs. 3 and. 4.

. The rods 13 and 5 referably have their adjacent ends flattened as at14:, (Fig. 6) and said rods-are held in relation to .one

overlapping flattened portions .14. The sleeve 15 has a threadedaperture 16 in which there engages the threaded end 17 of an arm 18, thesaid threaded end 17 being utilized to positively hold the ends of thePatented Apr. 141, 191141..

'13 compleanother by a sleeve 15 which surrounds the v rods 13 and 5within the sleeve 15. I The arm 18 projects laterally through a recess19 in the end of the casin 1 adjoining the plate 12, and through as at20 in the door and which alines with the recess 19. The outer endportion of the arm 18 is turned inwardly to a position nearly parallelwith the adjacent faces of the door, as at 21, and its extremity isfashioned to coact with. a buffer plate 22 which is fitted upon the doorframe and which is provided with an inclined groove 23, .along which theend of the arm 18 rides as the door comes into its full open position.

As previously stated, when the door is closed, the weather strip is heldin projected relation and against the tension of the spring 8, by virtueof the engagement of the rod 13 against the adjacent door jamb. But whenthe door is opened, so that the rod 13 clears the door jamb, the spring8 acts to move the rod 5 and toretract the weather strip into the casing1, so that the weather strip does not interfere with the openingmovement of the door. However, when the door comes into full openposition, the extremity of the arm 18 engages the plate 22, as shown inFig. 5, and the effect of this engagement is two-fold. The first effectis that the openin movement of the door 1s gradually retarded orcushioned, the arm 18 and the plate 22 coacting as elements of a doorbufi'er and the spring 8 furnishing the cushioning action. The secondeifect of the engagement of the arm 18 with the plate 22 is that the rod5 is moved against the tension ofthe spring 8 and the weather strip isprojected from the casing l and is caused to bear upon the floor withsuflicient pressure or frictional engagement to prevent an accidentalclosin movement of the door. The engagement 0 the weather strip with thefloor, obviously, with an intentional closing movement of the door andwhen the closing movement of the door is initiated the spring 8 retractsthe weather strip into the casing 1, so that the I movement of the dooris not retarded, as

above explained.

Instead of using the rods 5 and 13, a single rod 5 could be used of alength ual to the combined length of the rods 5 an 13 shown. Thearrangement disclosed, however, is preferred, in that the rod 13 may beadjusted lengthwise relatively to the rod 5,

to compensate for such slight variations as may be found in the distancebetween the adjoining faces of the door and the door jamb when the dooris in closed position.

Having fully described my invention, I claim: l

1. The combination with a door-having a bottom recess, of a Weatherstripmounted for vertical movement in said recess, operating means for. theweather strip including a rod slidable longitudinally of the recess,connections for transmitting the movements of the rod to the weatherstrip and a spring acting on the rod to hold the weather stripprojected, the rod having an end extension does not interfere which,when the weather strip is projected, projects beyond the door to engagethe adjacent door jamb as the door comes into closed osition, and an armprojecting laterally rom the rod, the door having a slot through whichthe arm projects, and the arm having an inturned end portion beyond thedoor.

2. The combination with a door having a bottom recess, of a weatherst-ri'p mounted for vertical movement in said recess, operating meansfor the weather strip including a rodslidable longitudinally of therecess, connections for transmitting the movements of the rod to theweather strip and-a spring acting on the rod to hold the weather stripprojected, the rod h aving an end extension adjustably connected theretowhich, when the weather strip is projected, projects beyond the door toengage the adjacent door jamb as the doorcomes into closed position, andan arm projecting laterally from the rod, the door having a .slotthrough which the arm projects, and the arm having an inturned endportion beyond the door.

3. The combination with a door having a bottom recess, of a weatherstrip mounted for vertical movement in said recess, operating means forthe weather strip including a rod slidable longitudinally of the recess,con nections for transmitting the movements of the rod to'the weatherstrip and a spring acting on the rod to hold the weather stripprojected, the rod having an end extension adjustably connected theretowhich, when 100 the weather strip is projected, projects beyond the doorto engage theadjacent door jamb as the door comes into closed position,an arm projecting laterally from the rod, the door having a slot throughwhich the arm 105 projects, and the. arm having an inturned end portionbeyond the door, and a sleeve which surrounds the adjoining ends of therod and the adjustable extension thereof and into which the inner end ofthe arm is 110 threaded to engage said adjoining ends and to fix saidrod and its extension against relative movement.

4.
